In this paper the development of the new adaptive solver QUADFLOW is described. It is based on an integral concept and consists of a flow solver, a grid generation tool using parametric mapping based on B-splines, and local grid adaptation based on multiscale analysis. QUADFLOW has been designed to obtain a solution method for multidisciplinary problems in the field of aerospace engineering. The most important applications are the simulation of high-lift configurations and elastic wings in cruise configuration. A partitioned field approach is used for the solution to aeroelastic problems. In this article the finite volume solver and its inclusion into an aeroelastic solver are outlined. The results of the validation study and a new matrix-free Newton-Krylov method, offering potential to accelerate convergence, are presented.
